depends...do you a have a 3 piece airlock or a S-bubble type? Big difference in bubble production and ratio(s) from the amount of bubbles produced per minute per second in correlation to fermentation speed.

Bubble rate is unreliable. Yes it tells you something is going on, but not what or how well it's progressing.....

Oh and if you had read enough early guidance, you would be aware that for effective and properly monitored fermentation, a standards wine/beer hydrometer is necessary. Plus pH/Litmus strips for the appropriate range (2 to 5 pH) or a cheap pH meter are/is helpful.....

Counting bubbles can easily lead to incorrect presumption of readiness and result in bottle bombs........

Equally, your batch ? What's the point of the sugar ?
